The Chinese Herbal Medicine Li Qi Huo Xue Di Wan Ameliorates Ischemia or Hypoxia-Induced Cardiac Injury and Remodeling in the Heart Through a Mechanism Involving Reduction of Necroptosis.

Li Qi Huo Xue Di Wan (LQHXDW), a Chinese herbal medicine, is commonly used to treat symptoms such as palpitations, chest tightness, chest pain, and shortness of breath. However, its potential to reduce ischemia or hypoxia-induced cardiac injury and remodeling, along with the precise mechanisms involved, remains unclear. This study aims to investigate the effects of LQHXDW on cardiac injury and remodeling induced by ischemia or hypoxia, both in vivo and in vitro, and to elucidate the underlying mechanisms.

The Transcription Factor Suppresses Peel Coloration in Postharvest 'Guifei' Mango in Response to High Concentration of Exogenous Ethylene by Negatively Modulating .

Anthocyanin accumulation is regulated by specific genes during fruit ripening. Currently, peel coloration of mango fruit in response to exogenous ethylene and the underlying molecular mechanism remain largely unknown. The role of MiMYB8 on suppressing peel coloration in postharvest 'Guifei' mango was investigated by physiology detection, RNA-seq, qRT-PCR, bioinformatics analysis, yeast one-hybrid, dual-luciferase reporter assay, and transient overexpression.

Memory regulation in feeding habit transformation to dead prey fish of Chinese perch (Siniperca chuatsi).

Memory drove a critical process of feeding habit transformation in Chinese perch when they re-trained to eat dead prey fish. To investigate the regulatory mechanism of cAMP-response element-binding protein (CREB) signaling pathway on the memory of Chinese perch during feeding habit transformation, the phosphorylation levels of upstream signal proteins of CREB between the control group (trained once) and the experimental group (trained twice) were measured. The results illustrated that the re-training was correlated to phosphorylation of extracellular regulated protein kinase (ERK1/2) and calcium/calmodulin-dependent protein kinase II (CaMKII), and dephosphorylation of protein kinase A (PKA) of Chinese perch.

Carcass decay deteriorates water quality and modifies the nirS denitrifying communities in different degradation stages.

Corpse degradation may release amounts of hazardous materials (e.g., cadaverine, putrescine and ammonia) into surrounding areas, which deteriorate environments and result in nitrogen contamination.

A high-density genetic linkage map for Chinese perch (Siniperca chuatsi) using 2.3K genotyping-by-sequencing SNPs.

Chinese perch, Siniperca chuatsi (Basilewsky), is one of the most commercially important cultured fishes in China. In the present study, a high-density genetic linkage map of Chinese perch was constructed by genotyping-by-sequencing technique with an F1 mapping panel containing 190 progenies. A total of 2328 SNPs were assigned to 24 linkage groups (LGs), agreeing with the chromosome haploid number in this species (n = 24).

Mandarin fish (Sinipercidae) genomes provide insights into innate predatory feeding.

Mandarin fishes (Sinipercidae) are piscivores that feed solely on live fry. Unlike higher vertebrates, teleosts exhibit feeding behavior driven mainly by genetic responses, with no modification by learning from parents. Mandarin fishes could serve as excellent model organisms for studying feeding behavior.

Memory Function in Feeding Habit Transformation of Mandarin Fish ().

Mandarin fish refuse dead prey fish or artificial diets and can be trained to transform their inborn feeding habit. To investigate the effect of memory on feeding habit transformation, we compared the reaction time to dead prey fish and the success rate of feeding habit transformation to dead prey fish with training of mandarin fish in the 1st experimental group (trained once) and the 2nd experimental group (trained twice). The mandarin fish in the 2nd group had higher success rate of feeding habit transformation (100%) than those in the 1st group (67%), and shorter reaction time to dead prey fish (<1 s) than those in the 1st group (>1 s).

Isolation and characterization of novel genomic and EST-SSR markers in Coreoperca whiteheadi Boulenger and cross-species amplification.

We described and characterized 11 expressed sequence tag (EST)-derived simple sequence repeats (SSR) and seven genomic (G)-derived SSRs in Coreoperca whiteheadi Boulenger. The EST-SSRs comprised 62.2% di-nucleotide repeats, 32.
